Of this group, everyone had HBcAb positive, HBsAg, HBsAb and HBVDNA negative status prior to start NHL therapy. Five patients were treated with Rituximab-containing protocols and five without. The mean time to HBV reactivation was 26,67 (±12,21) weeks. The mean time to HBV recovery (HBVDNA negativization and normal ALT) was 5,71 (±2,06) weeks. Five patients had HBsAg negativization after a mean time of NUC therapy of 37,80 (±11,78) weeks and stopped NUC therapy. Five patients were already in NUC therapy at the end of follow-up, due to HBV infection persistence (HBsAg positivity) and/or NHL relapse. Patient 7 to 10 have missing data, because of the retrospective nature of this study.
